This work focuses on preparing NaY zeolite using alternative sources of silica and modifying the zeolite with the surfactant cetyltrimethylammonium bromide. Two different hydrothermal synthesis routes were employed: the conventional method using sodium silicate as the silica source, and the other is a sustainable approach using vermiculite clay as the silica source. In traditional zeolite synthesis, sodium silicate is often used as the source of silica. However, . The vermiculite was subjected to an acid treatment, [...]

The assessment of mental health and mental disorders has undergone extensive exploration within the field of psychology, resulting in various models and approaches. In addition to traditional ways like the Diagnostic and Statistical Manual of Mental Disorders, psychologists have proposed alternative perspectives for evaluating mental health. One such innovative approach is the psychosocial health model, which defines mental well-being as sexual, emotional, social, environmental, cognitive, religious, moral, and spi [...]

The understanding of mental deterioration associated with old age has undergone several changes over the past two centuries, and has spurred major scientific debates. In the 19th century, this disorder was still considered an inevitable part of aging. The beginning of the 20th century offered a histological explanation for presenile dementia, and Alois Alzheimer was credited as the discoverer of a new disease that bears his name to date. In the last quarter of the 20th century, findings of Alois Alzheimer were appl [...]

Crystalline lithium fluoride (LiF) has been intensively pursued as potential alternative solid electrolytes (SEs) owing to its excellent chemical and electrochemical oxidation stability, and good deformability. However, due to its low ion conductivity, LiF is still challenging for practical SE applications. Herein, Li-Zr-F composite-based SE by liquid-mediated synthesis is proposed to be studied. methanol (CH3OH) was mainly evaluated as a liquid-mediated precursor for synthesizing Li-Zr-F composites under the stoic [...]

A range of corrective surgical procedures may be required in adult renal transplant recipients who sustain loss of integrity of the abdominal wall in the first month postoperatively. Where this involves the fascia, such as in acute fascial dehiscence or in renal allograft compartment syndrome, more sophisticated reconstructive procedures may also be required, particularly in the setting of surgical site infection. There is limited data on the use of prosthetic or biologic mesh for this type of scenario, where urgen [...]

The perinatal period represents a unique developmental window for families and an opportunity to reach and engage fathers in research and preventive interventions. The distinctiveness of this period stems from the changes and stressors that parents experience which affect their openness to enroll in interventions (e.g., adaptive parenting, physical and mental health, relationship skills, and economic self-sufficiency) and participate in research. While long understudied, paternal research in the perinatal period ha [...]

Mindfulness-Based Stress Reduction (MBSR) is an evidence-based health education program for medical patients with a variety of chronic conditions. MBSR also benefits health care providers themselves, decreasing work-related stress and preventing burnout. The objectives of this study were to describe an abbreviated MBSR curriculum developed for health care providers and to present initial program evaluation data assessing acceptability and outcomes. This program was implemented outside the research context with an o [...]

Gliomas originating from glial cells comprise about 30% of all primary central nervous system tumors and 80% of malignant brain tumors. Gliomas differ in their biological activity and are categorized according to grades, from benign to malignant with high recurrence rates. For diagnosis, location and extent of the tumor is assessed by CT and MRI, but for grading, additional parameters are necessary: contrast enhanced CT and MRI reveal damage of the blood–brain barrier, perfusion-weighted MRI shows regional blood su [...]

Background: The application of hematopoietic cell transplantation for induction of immune tolerance has been limited by toxicities associated with conditioning regimens and to graft-versus-host disease (GVHD). Decades of animal studies have culminated into sufficient control of these two problems, making immune tolerance a viable alternative to life-long application of immunosuppressive drugs to prevent allograft rejection. Methods: Studies in mice have paved the way for the application of HCT with limited toxicity [...]

Chronic inflammatory diseases are the most significant cause of death in the world and entail severe impairment to quality of life. The World Health Organization (WHO) ranks chronic inflammatory diseases as the greatest threat to human health and wellbeing. Inflammation is epicentral to many clinical conditions and symptoms, and it is anticipated that the health, economic, and mortality burdens associated with chronic inflammation will steadily increase in the United States over the next 30 years. An inflammatory m [...]
